From the table, we see that the values in the second column are 5 more than 10 times the values in the first column. If we state this as a mathematical expression, we say that $y = 10x+5$. $(5, 55), (6, 65), (7, 75)$
Work Step by Step
Since we have the equation $y=10x+5$, to extend this to $x=5, 6$, and $7$, we can plug in the $x$-values in the equation. Hence, $55=10\cdot 5+5, 65=10\cdot 6+5$, and $75=10\cdot 7+5$. If we write the solutions as ordered pairs, then we get $(5, 55), (6, 65)$, and $(7, 75)$.
